A composite ball bat includes multiple failure planes within a barrel wall. By including multiple failure planes in a barrel wall, the bat exhibits a drop in performance when subjected to rolling or other extreme deflection, with no temporary increase in barrel performance. Because the barrel performance does not increase, the ball bat is able to comply with performance limitations imposed by regulatory associations.

A swing practice device for emitting light at impact through self-generation enables an impact moment to be checked with the naked eyes without needing a battery by emitting light at an impact time point through self-generation during swinging by using a golf club, a baseball bat, and the like. The swing practice device includes a power generation magnet provided to a shaft so as to slide in the longitudinal direction of the shaft during swinging; a power generation coil provided on the circumference of a section in which the power generation magnet moves; a light-emitting lamp connected to the power generation coil so as to be turned on by the movement of the power generation magnet; and a magnet control means for preventing the movement of the power generation magnet at a set swing speed or lower.

A resilient rod that provides adjustable directional resistance is disclosed. In one aspect of the invention, a resistance level may be determined based on a thickness of the rod and a position of an applied force with respect to a fulcrum point. In another aspect of the invention, at least one spine may be attached to the beam to increase a diameter of the beam along one axis. The resistance level may be determined based on the thickness of the rod, the position of the applied force and an orientation of the at least one spine with regard to the direction of the applied force. In other aspects of the invention, the resilient rods may be incorporated into a golf club that provides for adjustable resistance levels.

A sporting device designed to help improve and teach a person as well as a trainer the correct wrist snap motion for playing many sports. This device is comprised of an adjustable wrist band that will adjust to the person's lower ulna and radius bones. with a resistance, adjustable strap around the finger/knuckle that connects from the finger/knuckle to the wrist strap. This device has an audible unit and can also have a vibration attachment as well as a counting attachment added to the wrist strap for different uses in sports or physical therapy. When the trainee is training they will make the same motion they would when they are playing said sport. This device can be set at a desired level of resistance and distance for desired wrist snapping motion. The trainee or trainer can set the desired wrist snapping motion for the device objective. When the objective is achieved the unit will respond with either a sound and or a vibration to indelicate that the desired motion was reached.

A device (e.g., an article of athletic gear) comprising a post-molded expandable component, which is a part of the device that is configured to be expanded or has been expanded after being molded. This may allow the post-molded expandable component to have enhanced characteristics (e.g., be more shock-absorbent, lighter, etc.), to be cost-effectively manufactured (e.g., by using less material and/or making it in various sizes), and/or to be customized for a user (e.g., by custom-fitting it to the user).

A ball bat extending about a longitudinal axis and includes a handle portion, a barrel portion, an injection molded element, and a tubular insert. The handle portion has a generally uniform outer diameter. The barrel portion has proximal and distal regions spaced apart by a central region. The element includes a tubular inner wall defining a longitudinal bore. The element is non-removably attached to the handle member. The element includes a tapered proximal region, a barrel engaging region, and an insert engaging region for engaging the insert. The insert engaging region includes a stop for inhibiting longitudinal movement of the insert. The barrel engaging region non-removably engages the proximal region. The bat having a total length measured from a proximal end of the handle portion to a distal end of the barrel portion. The handle portion has a length that is less than 70 percent of the total length.

An apparatus for engagement with a barrel of a bat includes a cup and at least one cover. The cup is secured for securement to a distal end of the barrel of the bat. The cup defines a cavity and includes a first connector portion. The at least one cover has a second connector portion cooperating with the first connector portion to releasably secure the cover to the cup over the cavity.

A baseball or softball bat includes a barrel extending from a handle. A chamber is formed in the bat, such as in the knob attached to the handle, or an end cap attached to the barrel. A liquid or gel at least partially fills the chamber and dissipates vibrations created when the bat strikes an object.

An American style football including an inflatable bladder, a cover surrounding the bladder, a battery carried by the football, and a light emitter. The light emitter is carried by the football and is electrically connected to the battery. At least a portion of the cover transmits light from the light emitter.

The present invention provides a lightweight glove for baseball or softball that may include an elastic backfinger to provide a conforming fit to the wearer's hand. In general, the elastic backfinger may replace existing, often leather backfingers, the back panel, the liner, and/or other elements of traditional gloves glove with the elastic material, combination of elastic materials, or combination of elastic and inelastic materials.
